Garza D, Hildebrand MS, Penington AJ, Brown N, de Silva MG. Australian healthcare professionals' perspectives on genetic counseling and genetic diagnosis in vascular anomalies. J Genet Couns 2024; 33:677-688. [PMID: 37632295 DOI: 10.1002/jgc4.1776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 08/13/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023]
Abstract
Genomic technologies are now utilized for the genetic diagnosis of vascular anomalies. This provides the opportunity for genetic counselors to make a significant contribution to patient care for this complex disease. The aim of this study was to explore Australian healthcare professionals' perspectives on the relatively recent integration of molecular diagnostic testing for vascular anomalies, with or without genetic counseling support. Nine semi-structured interviews were conducted with Australian healthcare professionals involved in the provision of care for individuals with vascular anomalies. Thematic analysis identified six themes: (1) Molecular diagnosis is beneficial; (2) psychosocial needs can motivate families to pursue a molecular diagnosis; (3) molecular genetic testing for vascular anomalies is complex; (4) genetic service provision is not a one size fits all; (5) a client-centered approach for genetic service provision can go a long way; and (6) the value of genetic counselors. Based on our findings, implementation of a vascular anomalies genetic diagnostic program inclusive of genetic counseling may be challenging, yet such programs are likely to benefit both patients and their families, as well as healthcare professionals. As this paradigm shift unfolds, genetic counselors have an opportunity to contribute to the vascular anomaly field by educating healthcare professionals and patients, by participating in multidisciplinary clinics to support complex cases and by raising awareness regarding their practice and potential contributions.

Abstract
OBJECTIVE To evaluate the safety and efficacy of bleomycin polidocanol foam (BPF) sclerotherapy for venous malformations (VMs) and analyze the associated clinical outcomes and predictors. METHODS We retrospectively assessed BPF sclerotherapy outcomes in 138 patients with VMs. We analyzed pain levels, lesion volume reduction, and subjective perception of response. Logistic regression analysis was performed to identify potential predictors of treatment outcome. Additionally, we carefully monitored and recorded complications. RESULTS There was a notable average reduction in lesion volume by 78.50% ± 15.71%. The pain numerical rating scale (NRS) score decreased from 4.17 ± 2.63 prior to treatment to 1.05 ± 1.54 afterward, and 70.3% of the patients experienced effective relief after a single BPF treatment. Multivariate analysis revealed that a high baseline NRS (odds ratio [OR]: 4.026) and elevated activated partial thromboplastin time (APTT, OR: 1.200) were positive predictors of pain reduction. Additionally, a high baseline NRS score (OR: 1.992) and elevated thrombocytocrit (PCT, OR: 2.543) were positive predictors of incomplete postoperative pain relief. Minor complications occurred in 31 (22.46%) patients. CONCLUSION BPF sclerotherapy is safe and effective for VMs, resulting in significant reduction in lesion volume, improved symptoms, and minimal complications. APTT and PCT levels are important predictors of pain outcomes following BPF treatment.

Abstract
Vascular anomalies (VA) are developmental anomalies of veins, arteries, lymphatics or capillaries thought to be caused by mutations in genes that drive angiogenesis. Treatments targeting these genes are limited. We review the literature for conventional medications and products from traditional medicine cultures that have been found to have antiangiogenic activity. Fewer than 50 drugs with credible human activity in VA were identified and include β blockers, monoclonal antibodies, microtubule inhibitors, multi-kinase inhibitors, PIK3CA- and RAS-MAPK pathway inhibitors, and thalidomides. Other drug categories of potential interest are ACE-inhibitors, antifungals, antimalarials, MMP9-inhibitors, and over-the-counter compounds used in Eastern traditional medicine. Low toxicity for some offers the possibility of combined use with known effective agents. In addition to already familiar drugs, others with antiangiogenic capabilities already in use in children or adults may deserve further attention for repurposing for VA.

Abstract
Background Aberrantly activated mammalian target of rapamycin complex 1 (mTORC1) plays a vital role in tumor angiogenesis, but its precise mechanisms are still unclear. Methods Micro-RNA-130b-3p (miR-130b-3p) expression in mTORC1-activated and control cells was examined by quantitative real-time PCR (qRT-PCR). MiR-130b-3p levels and their correlation with mTORC1 activity were evaluated by analyzing publicly available databases and in-house head and neck squamous cell carcinoma (HNSCC) tissues. The role of miR-130b-3p in mTORC1-mediated angiogenesis and tumor growth was examined using tube formation assay, chicken chorioallantoic membrane assay, cell line − derived xenograft models, and an HNSCC patient-derived xenograft (PDX) model. The regulatory mechanisms among signal transducer and activator of transcription 3 (STAT3), miR-130b-3p, and muscleblind-like protein 1 (MBNL1) were investigated via bioinformatics analyses, qRT-PCR, western blot, RNA immunoprecipitation, immunofluorescence, luciferase reporter assay, and chromatin immunoprecipitation assay. Results Elevated miR-130b-3p enhanced the angiogenic and tumorigenic abilities of mTORC1-activated cells both in vitro and in vivo. STAT3, a downstream effector of mTORC1, transactivated miR-130b-3p by direct binding promoter of the miR-130b gene. MBNL1 was identified as a direct target of miR-130b-3p. MBNL1 depletion rescued the compromised angiogenesis and tumor growth caused by miR-130b-3p inhibition. MiR-130b-3p levels were significantly upregulated and positively correlated with mTORC1 signaling in multiple cancers. MiR-130b-3p inhibition attenuated tumor angiogenesis and growth in an HNSCC PDX model. MBNL1 feedback inhibited STAT3 activation in mTORC1-activated cells. Conclusions The STAT3/miR-130b-3p/MBNL1 feedback loop plays a vital role in mTORC1-mediated angiogenesis and tumor progression. This pathway could be targeted for therapeutic intervention of mTORC1-related cancers.

Abstract
With the development of precision medicine, antigen/antibody-targeted therapy has brought great hope to tumor patients; however, the migration of tumor cells, especially a small number of cells flowing into blood or other tissues, remains a clinical challenge. In particular, it is difficult to use functional gold nanomaterials for targeted clinical tumor diagnosis while simultaneously obtaining stable and highly sensitive Raman signals. Therefore, we developed a detection method for functional Au Nanostars (AuNSs) with dual signal enhancement that can specifically track location and obtain high-intensity surface-enhanced Raman scattering (SERS) signals. First, AuNSs with specific optical properties were synthesized and functionalized. The Raman dye 4-mercapto-hydroxybenzoic acid and polyethylene glycol were coupled with the tumor marker, epidermal growth factor receptor, to obtain the targeted SERS probes. In addition, a detection chip was prepared for Raman detection with physical enhancement, exhibiting a 40-times higher signal intensity than that of quartz glass. This study combines physical enhancement and SERS enhancement technologies to achieve dual enhancement, enabling the detection of a highly sensitive and stable Raman signal; this has potential clinical value for antigen/antibody-targeted tumor diagnosis and treatment.

Abstract
BACKGROUND AND OBJECTIVE Kaposiform hemangioendothelioma (KHE) is a rare, aggressive and borderline vascular tumor mainly occurring in infants and children. The aim of this study was to determine the health-related quality of life (HRQOL) in children with KHE. MEASURES A total of 91 children with KHE participated in this cross-sectional study. The HRQOL was assessed by the age-specific Pediatric Quality of Life Inventory Version 4.0 (PedsQL™ 4.0) Infant Scales, Family Information Form (FIF), Family Impact Module (FIM) and Generic Core Scales (GCS). For comparison, demographically matched healthy children were recruited as a control group. The main outcome measure of HRQOL was analyzed in the two groups. We determined related factors that influenced the HRQOL in children with KHE and their parents by using a stepwise multiple regression analysis. RESULTS The study found that the scores of each item in the family impact module (FIM) were lower than 75, which suggesting that KHE can make the parents of patients in a state of poor quality of life. The scores of physiological and psychosocial domains in all age groups of patients with KHE were lower than those of normal children (P < 0.01). Activity dysfunction is the factor influencing the physiological function score of all-age patients. KMP is the factor influencing the psychosocial function score of all-age patients. CONCLUSIONS The findings presented here suggest that patients with KHE have a poor HRQOL. KMP and activity dysfunction are risk factors for poor HRQOL in patients with KHE. However, lesion size, lesion location and education level of the mother and father were not related to the HRQOL.

Abstract
Abstract
Background
Various high-powered magnetic toy sets constitute a major hazard as the small magnets can be easily swallowed or aspirated by young children. Multiple ingested magnets or the ingestion of a magnet with another metallic object can pose a serious threat as this may lead to bowel perforation, fistulation, intestinal volvulus, bowel obstruction and death.
Main body
Retrieval of ingested magnets from the stomach is routinely performed endoscopically but can become a painstaking quest involving many tedious attempts to secure the magnet(s). Historically, pre-routine endoscopy, magnetic retrievers were used under fluoroscopic control for the removal of metallic objects in the stomach. With the advent of endoscopic retrieval instruments, they fell out of favour and are no longer readily available on the market. Despite this, conventional endoscopic instruments are likely to be less effective than endoscopic-assisted magnetic retrievers due to confounding weak bonds which form between the metal retrieval device and the magnet.
Preoperative testing, and selection of the retrieval instrument with the strongest coupling effect with a magnet, might be beneficial. A simple, endoscopic-assisted magnetic retriever created in theatre can allow for more effective, time-efficient and safe removal of ingested magnets under direct vision.
Conclusion
Urgent removal of multiple ingested magnets or a single ingested magnet coupled with another ingested metallic object should be highlighted. Stricter implementation of a widespread ban over loose magnetic toys is needed. Standardised protocols for the surgical management of ingested magnets should be available in every hospital.

Abstract
Arterio-venous malformation (AVM) is a congenital disorder of blood vessels, causing abnormal passage of blood between the artery and vein, which most often results in abnormal development of the vascular system in embryonic life. Arteriovenous malformations of the head and neck pose a challenging therapeutic and reconstructive problem. We present a rare case of a 22-year-old white woman, who complained of facial asymmetry on the right side, evolving after an episode of jugular cellulite of dental origin treated 6 months ago. Clinical examination revealed a palpable nodule measuring approximately 25 mm, soft, painless, of sub-mucosal location and a swollen, bluish right hemi tongue. Ultrasonography was requested, which indicated the hypothesis of a vascular lesion. The microscopic diagnosis was of arterio-venous malformation with thrombus formation. The patient has been followed for 3 months and is without signs of relapse. We treated the cellulite and closely followed the patient.

Abstract
Laser surgery is becoming an increasingly efficacious and customizable treatment modality for the management of pediatric vascular lesions. Proper use requires a thorough understanding of the scientific principles of laser surgery and knowledge of the various lasers available. Moreover, each laser has a multitude of settings that can be employed to properly target the lesion at hand. Each patient will present with unique challenges and variations in the presentation of their vascular lesion. This requires understanding of the most effective laser to use for each lesion and the factors that may alter the desired device settings. Using key search terms, a literature search was conducted on laser surgery for pediatric vascular lesions using PubMed/MEDLINE and Embase for articles published in English or French. Ultimately, 52 articles met our search criteria. The laser indications, limitations, and settings utilized for each type of vascular lesion were compiled for the purposes of this summative review. Laser surgery is an effective and appropriate option for the treatment of certain pediatric vascular lesions. Knowledge of optimal device parameters in every setting is essential to good clinical practice.

Abstract
Angiogenesis plays an important role in the occurrence and development of skin tumors and vascular anomalies (VAs). Many drugs have been adopted for the inhibition of angiogenesis, among which rapamycin (RAPA) possesses good application prospects. However, the clinical potential of RAPA for VAs is limited by its poor solubility, low bioavailability, and high cytotoxicity. To extend its application prospect for VAs treatment, in this study, we develop RAPA-loaded dissolving polymeric microneedles (RAPA DMNs) made of polyvinylpyrrolidone (PVP) due to its excellent solubilizing ability. RAPA DMNs are shown to have sufficient mechanical strength to overcome the skin barrier of the stratum corneum and could deliver RAPA to a depth of 200 μm. The microneedle shafts completely dissolve and 80% of the drug could be released within 10 min after insertion ex vivo. The DMNs-penetrated mice skin could repair itself within 4 h after the application of RAPA DMNs. RAPA DMNs also show good anti-angiogenic effect by inhibiting the growth of human umbilical vein endothelial cells (HUVECs) and decreasing the secretion of vascular endothelial growth factor (VEGF). Therefore, RAPA DMNs promisingly provide a safe and efficient approach for VAs treatment.

Abstract
Intracerebral arteriovenous malformations (AVMs) are high-flow collections of abnormal vessels and a common cause of pediatric intracranial hemorrhage. There are few treatment options available for AVMs not amenable to surgical resection, endovascular embolization, radiosurgery, or multimodality treatment. The authors sought to review the molecular and genetic pathways that have been implicated in the formation of AVMs, focusing on the possibility of medically targeting these pathways in the treatment of AVMs. In the novel case presented here, a pediatric patient who was diagnosed with an intracranial AVM unamenable to conventional treatments underwent alternative treatment with molecular pathway inhibitors.

Abstract
The aim of the present retrospective study was to investigate the clinical safety and efficacy of absolute ethanol combined with n-butyl cyanoacrylate sclerotherapy in the treatment of Puig's classified advanced venous malformation. Sclerotherapy was performed in 121 children (52 males and 69 females; age range, 5 months to 16 years) with venous malformations under general anesthesia between April 2009 and October 2014 at the Department of Interventional Radiology and Vascular Anomalies, Guangzhou Women and Children's Medical Center, Guangzhou, China. The patients with venous malformations were diagnosed and classified according to the diagnostic criteria of the International Society for the Study of Vascular Anomalies. According to the characteristics of intraoperative percutaneous angiography, 21 patient cases (9 males and 12 females; age range, 6 months to 14 years) were classified as advanced Puig's venous malformation. These 21 patients were treated with absolute ethanol combined with n-butyl cyanoacrylate. The patients were followed-up for 6–24 months (average, 15 months) after treatment. Following treatment with absolute ethanol combined with n-butyl cyanoacrylate, 15 cases were controlled and the total effective rate was 71% (15/21). However, 1 patient developed skin ulcerations, which was classed as a minor complication, 1 patient developed ectopic embolism caused by n-butyl cyanoacrylate reflux, and 1 patient developed transient pulmonary hypertension, the latter two complications were classified as major. Notably, the incidence rate of minor and major complications were 14.3%. To conclude, the present findings indicated that absolute ethanol combined with n-butyl cyanoacrylate sclerotherapy was a safe and effective method with a low complication rate in the treatment of Puig's classified advanced venous malformation in patients.

Abstract
Notch expression has been shown to be aberrant in brain arteriovenous malformations (AVM), and targeting Notch has been suggested as an approach to their treatment. It is unclear whether extracranial vascular malformations follow the same patterning and Notch pathway defects. In this study, we examined human extracranial venous (VM) (n = 3), lymphatic (LM) (n = 10), and AV (n = 6) malformations, as well as sporadic brain AVMs (n = 3). In addition to showing that extracranial AVMs demonstrate interrupted elastin and that AVMs and LMs demonstrate abnormal α-smooth muscle actin just as brain AVMS do, our results demonstrate that NOTCH1, 2, 3 and 4 proteins are overexpressed to varying degrees in both the endothelial and mural lining of the malformed vessels in all types of malformations. We further show that two gamma secretase inhibitors (GSIs), DAPT (GSI-IX) and RO4929097, cause dose-dependent inhibition of Notch target gene expression (Hey1) and rate of migration of monolayer cultures of lymphatic endothelial cells (hLECs) and blood endothelial cells (HUVEC). GSIs also inhibit HUVEC network formation. hLECs are more sensitive to GSIs compared to HUVEC. GSIs have been found to be safe in clinical trials in patients with Alzheimer’s disease or cancer. Our results provide further rationale to support testing of Notch inhibitors in patients with extracranial vascular malformations.

Abstract
BACKGROUND Curcumin has been used as an alternative medicine for the treatment of infantile hemangiomas (IHs); however, the mechanism underlying the effectiveness of curcumin in IHs remains largely unclear. METHODS In this study, we isolated primary human hemangioma endothelial cells (HemECs) from fresh surgical specimens of 3 patients. We treated HemECs by curcumin and investigated the alterations in proliferative and apoptotic signaling pathways with cell counting kit-8, flow cytometry, western blotting, immunofluorescence, and real-time polymerase chain reaction. RESULTS AND CONCLUSION We found that curcumin potently inhibited proliferation in HemECs, achieving low-micromolar IC50 (the half maximal inhibitory concentration) value. We also observed that treatment with curcumin induced apoptosis in HemECs, as evidenced by positively Annexin-V-FITC staining, caspase-3 activation, and cleavage of poly(adenosine diphosphate-ribose) polymerase (PARP) in the treated cells. Moreover, we showed that curcumin suppressed the expression of antiapoptotic protein myeloid cell leukemia-1 (MCL-1), hypoxia-inducible factor 1α (HIF-1α), and vascular endothelial growth factor (VEGF).Altogether, our study suggests that the effectiveness of curcumin in IHs may be associated with its potent antiproliferative and apoptotic activities in HemECs.

Abstract
Abstract
The understanding of the physiology of cerebral arteriovenous malformations (AVMs) continues to expand. Knowledge of the hemodynamics of blood flow associated with AVMs is also progressing as imaging and treatment modalities advance. The authors present a comprehensive literature review that reveals the physical hemodynamics of AVMs, and the effect that various treatment modalities have on AVM hemodynamics and the surrounding cortex and vasculature. The authors discuss feeding arteries, flow through the nidus, venous outflow, and the relative effects of radiosurgical monotherapy, endovascular embolization alone, and combined microsurgical treatments. The hemodynamics associated with intracranial AVMs is complex and likely changes over time with changes in the physical morphology and angioarchitecture of the lesions. Hemodynamic change may be even more of a factor as it pertains to the vast array of single and multimodal treatment options available. An understanding of AVM hemodynamics associated with differing treatment modalities can affect treatment strategies and should be considered for optimal clinical outcomes.

Abstract
Loss-of-function (LOF) mutations in the endothelial cell (EC) enriched gene endoglin (ENG) causes the human disease hereditary haemorrhagic telangiectasia-1, characterized by vascular malformations promoted by vascular endothelial growth factor A (VEGFA). How ENG deficiency alters EC behaviour to trigger these anomalies is not understood. Mosaic ENG deletion in the postnatal mouse rendered Eng LOF ECs insensitive to flow-mediated venous to arterial migration. Eng LOF ECs retained within arterioles acquired venous characteristics and secondary ENG-independent proliferation resulting in arterio-venous malformation (AVM). Analysis following simultaneous Eng LOF and overexpression (OE) revealed that ENG OE ECs dominate tip cell positions and home preferentially to arteries. ENG knock-down altered VEGFA-mediated VEGFR2 kinetics and promoted AKT signalling. Blockage of PI3K/AKT partly normalised flow-directed migration of ENG LOF ECs in vitro and reduced the severity of AVM in vivo. This demonstrates the requirement of ENG in flow-mediated migration and modulation of VEGFR2 signalling in vascular patterning.

Abstract
Venous malformations (VMs) are congenital vascular malformations. They are very often misnamed and thus incorrectly managed. The aim of the present paper is to provide the reader with the most updated literature available and to offer a detailed description of each single aspect of this disease. In detail, the paper discusses the epidemiology, the embryological origins and the physiopathology of VMs. Then, the clinical features of sporadic, inherited and syndromic VMs are discussed. The instrumental diagnosis is presented, and the role of US, CT, MRI and phlebography is pointed out. Differential diagnoses with other vascular malformations and tumors are described. The clinical session ends with the staging of VMs relying on MRI and rheological features. All aspects of treatment are described: conservative measures, medical treatment, sclerotherapy, laser and surgery are thoroughly discussed. A section is reserved to bony VMs. Their clinical aspects and the appropriate treatment are presented.

Abstract
Vascular anomalies are broadly divided into vascular tumours and malformations. These lesions are composed of abnormal vascular elements of various types, and mainly affect infants, children, and young adults. Vascular anomalies may be painful, may be complicated by bleeding, infection, or organ dysfunction, and can have secondary effects on other tissues. Current treatment strategies include surgical excision, pulsed laser, and sclerotherapy, which are invasive, with risks of recurrence. There are growing pharmacological options for these vascular anomalies, but, to date, no specific targeted therapies have been developed. Phosphoinositide 3-kinases (PI3Ks) constitute a family of lipid kinases that are involved in signal transduction and vesicular traffic, and that modulate important cellular processes such as proliferation, growth, and migration. Recent findings have indicated that the PI3K signalling pathway is important in the pathogenesis of vascular anomalies. This provides an opportunity to use PI3K inhibitors, which are in clinical trials for cancer treatment, for such lesions. Here, we provide an update on the classification of vascular anomalies, with their major features, and discuss the role of the PI3K signalling pathway in the pathogenesis of vascular anomalies, and their clinical implications and therapeutic opportunities.

Abstract
OBJECTIVE This study reviewed our experience in treating the recanalization of maxillary and mandibular arteriovenous malformations in children. STUDY DESIGN Four patients with maxillary or mandibular arteriovenous malformations (AVMs) were included in this study. All the patients had undergone multidisciplinary treatment of AVM at least 26 months before our review, including superselective intra-arterial embolization combined with bone wax packing. Computed tomographic angiography and digital subtraction angiography were performed to confirm the presence of recanalization. Superselective intra-arterial embolization combined with bone wax packing and tooth extractions were performed in the patients with recanalization. RESULTS After confirmation of the recanalization of AVM by digital subtraction angiography, the patients were treated with superselective intra-arterial embolization combined with bone wax packing and tooth extractions (if necessary). All the patients were followed up for 5 to 14 months, with an average of 9.5 months. The outcome for all patients was good, and no patient complained of pulsatile sensation or hemorrhage after treatment. CONCLUSIONS In the treatment for recanalization of maxillary and mandibular AVMs, reapplication of the superselective intra-arterial embolization, combined with bone wax packing, remains necessary.

Abstract
BACKGROUND Dysregulation of the mammalian target of rapamycin pathway is the underlying pathogenic mechanism in tuberous sclerosis complex (TSC). Other syndromes caused by genetic alterations in this pathway frequently manifest as vascular anomalies or asymmetric overgrowth. Rarely, these features have been documented in TSC. OBJECTIVE To collate cases of TSC with vascular anomaly or overgrowth that have been published and to assemble additional recent cases, as this finding has been underreported. METHODS TSC cases from three pediatric dermatology referral centers on two continents were reviewed to identify individuals noted to have hemihypertrophy or vascular anomalies. RESULTS We report five additional cases of TSC associated with vascular anomalies or overgrowth that contribute to our understanding of some of the pathways and treatments involved in vascular anomalies. CONCLUSION Hemihypertrophy and vascular anomalies may be more frequent in the setting of TSC than previously appreciated. A common pathogenetic mechanism may tie these manifestations together.

Abstract
Venous malformations (VM) are vascular malformations characterized by enlarged and distorted blood vessel channels. VM grow over time and cause substantial morbidity because of disfigurement, bleeding, and pain, representing a clinical challenge in the absence of effective treatments (Nguyenet al, 2014; Uebelhoeret al, 2012). Somatic mutations may act as drivers of these lesions, as suggested by the identification of TEK mutations in a proportion of VM (Limayeet al, 2009). We report that activating PIK3CA mutations gives rise to sporadic VM in mice, which closely resemble the histology of the human disease. Furthermore, we identified mutations in PIK3CA and related genes of the PI3K (phosphatidylinositol 3-kinase)/AKT pathway in about 30% of human VM that lack TEK alterations. PIK3CA mutations promote downstream signaling and proliferation in endothelial cells and impair normal vasculogenesis in embryonic development. We successfully treated VM in mouse models using pharmacological inhibitors of PI3Kα administered either systemically or topically. This study elucidates the etiology of a proportion of VM and proposes a therapeutic approach for this disease.

Abstract
Since publication of a single case report of lymphatic malformation improvement during sildenafil therapy for pulmonary hypertension, sildenafil use has propagated across multiple vascular anomalies diagnoses. Vascular anomalies are rare conditions, often with poor long-term outcomes from available therapies, making these patients vulnerable to novel therapy use. We have retrospectively reviewed 14 children with vascular anomalies treated with sildenafil. None of these patients reported improvement of disease while on treatment and some reported side effects including infections and bleeding. Pending more convincing prospective data, we recommend caution prior to sildenafil use for vascular anomalies.

Genitourinary and perineal vascular anomalies in children: A Seattle children's experience. J Pediatr Urol 2015; 11:227.e1-6. [PMID: 26163459 DOI: 10.1016/j.jpurol.2015.03.019] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Accepted: 03/06/2015] [Indexed: 11/23/2022]
Abstract
AIMS We sought to evaluate the initial presentation and diagnosis, to compare presenting symptoms of these anomalies with respect to location, and describe the management course and review the treatment outcomes of vascular anomalies (VA) in genitourinary and perineal area. We described changes in the evaluation and management approach over time. METHODS After IRB approval, we reviewed the Vascular Anomalies Program 3,780 patient database from 1998-2013, identifying 85 patients with GUP VA. Demographics, presentation, anatomic location, imaging modalities and treatments were reviewed. For the 76 patients that were managed at our institution, we analyzed data for management approach change over time, duration of follow-up, complications, and treatment outcomes. Using Chi-squared test, we analyzed the treatment eras for any difference in presenting symptoms, or management approach. RESULTS From the VAP database, we identified 85 patients with GUP VA. Vascular tumors (VT) were more common than vascular malformations (VM) (62/85, 72.9% vs. 23/85, 27.1%). The 62 patients with VT were subdivided into infantile hemangioma (IH) (49, 79%) and congenital hemangioma (CH) (13, 20.9%). The 23 patients with VM were subdivided into simple (18, 78.2%) and complex (2, 8.7%), and one patient had Klippel-Trenaunay syndrome. Overall, genital VA were more common than perineal (43/85, 54.2% vs. 24/85, 28.2%). None of our patients had urinary involvement. Ultrasound was used in 34% (29/85) of VA patients, the majority were VM (18/23, 78%). Majority of patients were symptomatic with ulceration, pain and bleeding (54/85, 63.5%). Malformations were more complex, presenting as extensive lesions (6/23, 26.1%), which included pelvic extension in 5 (21.7%). Seventy-six patients were managed at our institution. Treatment was utilized more frequently than observation overall (46/76, 60% vs. 30/76, 40%), and more frequently for VM than VT (12/18, 63% vs. 34/58, 57%). After introduction of oral propranolol for treatment of IH in 2010, fewer patients presented with ulceration (p = 0.213), and more were treated with propranolol over procedural therapy (p = 0.157). Overall, complete treatment of these lesions was achieved in 82.9% (63/76), with low complication rate (6/76, 7.9%). CONCLUSIONS Evaluation and management of VA is best performed with expert multidisciplinary team at tertiary care center. Imaging studies are mostly used in evaluation of VM. Symptomatic VA involving the perineum and genitalia require therapeutic management. With the introduction of propranolol for treatment of IH, oral therapies were used more often with excellent outcomes. A multidisciplinary approach is essential to treatment innovation, patient-centered therapies and improving therapeutic outcomes.

Initial Results of Image-Guided Percutaneous Ablation as Second-Line Treatment for Symptomatic Vascular Anomalies. Cardiovasc Intervent Radiol 2015; 38:1171-8. [PMID: 25823573 DOI: 10.1007/s00270-015-1079-2] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2014] [Accepted: 02/08/2015] [Indexed: 01/20/2023]
Abstract
PURPOSE The purpose of this study was to determine the feasibility, safety, and early effectiveness of percutaneous image-guided ablation as second-line treatment for symptomatic soft-tissue vascular anomalies (VA). MATERIALS AND METHODS An IRB-approved retrospective review was undertaken of all patients who underwent percutaneous image-guided ablation as second-line therapy for treatment of symptomatic soft-tissue VA during the period from 1/1/2008 to 5/20/2014. US/CT- or MRI-guided and monitored cryoablation or MRI-guided and monitored laser ablation was performed. Clinical follow-up began at one-month post-ablation. RESULTS Eight patients with nine torso or lower extremity VA were treated with US/CT (N = 4) or MRI-guided (N = 2) cryoablation or MRI-guided laser ablation (N = 5) for moderate to severe pain (N = 7) or diffuse bleeding secondary to hemangioma-thrombocytopenia syndrome (N = 1). The median maximal diameter was 9.0 cm (6.5-11.1 cm) and 2.5 cm (2.3-5.3 cm) for VA undergoing cryoablation and laser ablation, respectively. Seven VA were ablated in one session, one VA initially treated with MRI-guided cryoablation for severe pain was re-treated with MRI-guided laser ablation due to persistent moderate pain, and one VA was treated in a planned two-stage session due to large VA size. At an average follow-up of 19.8 months (range 2-62 months), 7 of 7 patients with painful VA reported symptomatic pain relief. There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma-thrombocytopenia syndrome. There were two minor complications and no major complications. CONCLUSION Image-guided percutaneous ablation is a feasible, safe, and effective second-line treatment option for symptomatic VA.

Abstract
We report the case of an infant with severe lymphatic malformation necessitating ex-utero intrapartum treatment (EXIT) procedure and examine recent advances in high resolution ultrasonography and magnetic resonance imaging, which allow for improved prenatal diagnosis of lesions that cause critical airway obstruction in the neonate. Treatments for lymphatic malformations including surgical resection, sclerotherapy, coblation, and sildenafil are discussed. Our patient did not have any reduction in the size of the lymphatic malformation from sildenafil as suggested in another series.

Abstract
Lymphatic malformations (LMs) are developmental anomalies of the lymphatic system associated with the dysmorphogenesis of vascular channels lined by lymphatic endothelial cells (LECs). Seeking to identify intrinsic defects in affected LECs, cells were isolated from malformation tissue or fluid on the basis of CD31 and podoplanin (PDPN) expression. LECs from five unrelated LM lesions were characterized, including cells derived from one patient previously diagnosed with CLOVES. CLOVES-related LECs carried a known, activating mutation in PIK3CA (p.H1047L), confirmed by direct sequencing. Activating PIK3CA mutations (p.E542K and p.E545A) were identified in lesion-derived cells from the other four patients, also by direct sequencing. The five LM-LEC cultures shared a lymphangiogenic phenotype distinguished by PI3K/AKT activation, enhanced sprouting efficiency, elevated VEGF-C expression and COX2 expression, shorter doubling times and reduced expression of angiopoietin 2 and CXCR4. Nine additional LM-LEC populations and 12 of 15 archived LM tissue samples were shown to bear common PIK3CA variants by allele-specific PCR. The activation of a central growth/survival pathway (PI3K/AKT) represents a feasible target for the non-invasive treatment of LMs bearing in mind that background genetics may individualize lesions and influence treatments.

Abstract
Introduction Kasabach-Merritt syndrome (KMS) is a life-threatening disease. We describe a combined medical and multistep, endovascular embolization that was successfully performed with surgery. Case Report A 40-day-old female baby was referred because of an infiltrating pelvic mass. Blood tests showed severe anemia and thrombocytopenia with consumptive coagulopathy. The clinical aspect was pathognomonic for KMS. Administration of steroids and chemotherapy were started and coagulation parameters were normalized with tumor volume regression. Three months later, elective surgical treatment became possible, and dissection and ligature of the left internal iliac artery and sacral artery were performed. The main arterial supply of the mass was embolized with Spongostan®. Two months later, a second hybrid approach was adopted for embolization of the main vascular supply of the tumor occupying the left thigh. Via a third contralateral hybrid femoral approach and under fluoroscopy, selective catheterization of the left profunda femoris artery was performed. The arterial feeder of the tumor, localized at the left gluteus, was seen on a CT scan 2 months later and was embolized with Onyx-18. Conclusion Chemotherapy and a tailored hybrid approach comprising repeated endovascular embolizations seem to be a safe treatment in cases of unresectable and life-threatening tumors in small babies.

Abstract
Hemangiomas of the articular synovium are rare and commonly associated with recurrent joint swelling and painful limitation of motion. The knee joint is the most commonly involved site, with most patients diagnosed in the second to third decade of life. Although over 200 cases have been reported in the English-language medical literature, only three have originated within the hip joint, all of which were in adult patients reported in the surgical literature. We describe a histologically proven synovial hemangioma of the hip joint in a pediatric patient that invaded the femur, acetabulum, and adjacent soft tissues, with a detailed discussion of the differential diagnosis based on the radiographic and magnetic resonance imaging (MRI) findings.
